CASE.

Application led July 5,

This invention relates to improvements in receptacles and has particular reference to a receptacle for an eyeglass or spectacle frame.

'E The principal object of this invention is to provide simple, efficient, inexpensive and ornamental means for providing a dustproof receptacle and to provide terminal abutments for the lining of the cover that will hold it in place and prevent it being displaced, fraying out, etc.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings, and it will be apparent that many changes in the details of construction and arrangement ofv parts may be made without departing from the spirit of the invention as expressed in the accompanying claims. I, therefore, do not wish 'to be limited to the exact details of construction shown and described, the preferred forms only having been shown by way of illustration.

Referring to the drawings:

Fig. 1 is a front view of a receptacle em,- bodying the invention.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a cross section on line 3 3 of Fig. 1.

Fig. 4 is a cross section on line 1 -4 of Fig. 2.

Prior to my invention the tops or lids of receptacles of this character were constructed so as to overlie flatly the base orr 1927. Serial N0. 203,351.

covered with cloth, leather or other material. It will be noted that in the cover 1 I have Y provided a knuckle or bend 6 at the 'outermost edge of the front of the cover where it overlies the lip l of the base 2. The object of this kunckle or bend is two-fold. In the first place it provides a square shoulder or retaining abutment for the end of the lining 5, guarding it against being pulled loose or fraying out. In the second place it provides a sharp edge engaging portion 7 for engaging the lip portion Ll. The p knuckle being in the form of a bent portion it is not as easily deflected or bent as an unknuckled member. This knuckling at 6 not only insures a tight engaging dust-proof contact at 7, but also insures that the contact will be maintained in service as it will not be bent away as in the prior art cases forming openings through which the dirt and dust may seep. n

From the foregoing it will be seen that I have provided simple, eficient and inexpensive means for carrying out all of the 0b-4 jects of the invention, and that I have thus secured a dust-proof receptacle which will maintain its dust-proof contact in service and at the same time provide a guard and protection Vfor the edge and end of the lining.

I-Iaving described my invention, I claim:

1. In a device of the character described, a basehaving a lip overlying a portion thereof, a cover having an inturned edge portion overlying the lip whereby the edge of the inturned portion engages the lip to I form a dust proof contact therewith, and a lining on the inside of the cover having one inturned portion engages the lip to form a dust proof Contact therewith, seid inturned edge portion forming a, stiffening member 10 along the line of Contact of the inturned kedg - ARTHUR J.
